Table 2 CD68+, CD3+, CD20+ and CD138+ cell counts on paired skin specimens in the 28 patients with SSc

From: Characterization of inflammatory cell infiltrate of scleroderma skin: B cells and skin score progression

  Clinically involved skin Clinically uninvolved skin P
CD68+ mean (SD) 26.3 (8.3)a 13.6 (6.1)a 0.001
CD68+ median (range) 24.5 (12.0–40.0) 12.5 (3.0–25.0)
CD3+ mean (SD) 71.7 (34.6)a 45.7 (36.0)a 0.001

CD20+ mean (SD)* 4.7 (5.9)b 1.9 (2.9)b 0.04
CD20+ median (range) 2.0 (0.0–25.0) 1.0 (0.0–11.5)
CD138+ mean (SD) 3.6 (2.3)a 1.9 (1.7)c < 0.001

  1. The values are the mean (SD) and median (range)
  2. aMean (SD) and median (range) of CD68+, CD3+, CD138+ in clinically involved skin (forearm) and of CD68+ and CD3+ in clinically uninvolved skin (buttock) refers to the duplicate skin samples from patients
  3. bMean (SD) and median (range) of CD20+ was calculated considering only the 17 patients (60.7%) that had almost one CD20+ cell in clinically involved skin or in clinically uninvolved skin
  4. cMean (SD) and median (range) of CD138+ in clinically uninvolved skin was calculated considering 25 out of 28 (89.3%) patients with CD138 + cells in uninvolved skin specimens
